View 2 RepliesForms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?
Feb 16, 2011Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Window Focus - Right Click On The NotifyIcon, Excel Gains Focus?
Mar 10, 2009Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.
View 1 RepliesForms :: Form Losing Focus - Keeps Loosing Focus ?
Nov 26, 2009I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

View 1 RepliesCan't Un-select DevExpress LookUpEdit?
Oct 28, 2010I have a DevExpress LookUpEdit that I am using withing Visual Studio 2008 in VB.Net. I have the LookUpEdit bound to my datasource and the value that it is displaying may be null or one of the rows in the datasource. My program displays a treelist and when a node is select the LookUpEdit is supposed to display the assigned value (could be null) and let the user reassign the value. I do have the LookUpEdit.Properties.AllowNullInput set to True. Right now when the program first starts if the first node in the treelist I choose has a null value the LookUpEdit displays nothing, if I change the value of the LookUpEdit the value changes in the database, if I change to a node that has a value for the LookUpEdit the value does display.
The problem is that if I switch from a node with a value to one without the LookUpEdit displays the previous value. I have gone through the debugger and it is still going through the fetch properly.
I have tried to reset the LookUpEdit.Text, LookUpEdit.EditValue and LookUpEdit.SelectedText but nothing works. I even replicated the conditions that the LookUpEdit has when it first displays nothing (LookUpEdit.Text = "" and LookUpEdit.EditValue = " ") but it still displays the last value.
[Code]...
The values are set. The problem is that in the act of setting the value the dropdown menu opens. So I get it to close with lueLocation.ClosePopup(). For some reason when it gets called it changes the .Text and .EditValue back to the previous values and thus calls the TextChanged Event.

How To Tell When DevExpress FindPanel Is Closed
Oct 4, 2011I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2. I just started programming with the WinForms XtraGrid FindPanel and so far it works wonders. However I was wondering if there is any way to know when the user closes the FindPanel. Right now if gridview.OptionsFind.AllowFindPanel is True and gridview.OptionsFind.AlwaysVisible is False then the user is able to click on the x and close the FindPanel. Is there anyway to catch this closing? I don't want to stop it just do a couple of things once it is hidden or closed.

View 3 RepliesLost Focus Event, What Control Is Getting Focus?
Mar 21, 2012I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

.net - Devexpress LookupEdit Is Not Displaying The Selected Row For The Last Row?
Jul 23, 2010I am using DevExpress.XtraEditors.LookUpEdit to display the information about the classes available. Currently it has 3 columns. The lookupedit is working perfectly except when I set the editValue to the last row. When the editvalue is set to any row other than the last one it shows the selected row when the lookupedit isn't opened yet when the lookupedit is set to the last row nothing is displayed.
[Code]...
Right now the lookupedit displays the selected text unless I select the last row, row number tableData.Rows.Count which then displays nothing. Yet when I print the values they are correct and when I remove the +1 when setting the lookupedit it sets it to the previous line I want an the first row can't be displayed.

Override The DevExpress Filter Choices In GridControl?
Oct 5, 2011I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2, specifically WinForms. In the DevExpress GridControl at runtime you can click on the right side of the column header and choose which values in the column you want to show. For example if your table contained:
Name1 Checked
Name2 Unchecked
Name3 Unchecked
Name4 Checked
Then if you click on the right side of the checkbox's header you can choose checked (or unchecked) and it would display only the data that is checked (or unchecked). In this case with checked you would have:
Name1 Checked
Name4 Checked
I was wondering if there was some way to override the names so instead of letting me choose checked or unchecked I could override it with 'owned' and 'rented' or 'active' and 'inactive' based on what the checkbox represents in that specific column.

Devexpress (10.2) GridControl Isn't Letting Null Value In Column?

I would like orientation or advice on how to proceed given the following:I execute an SQL statement, such as select * from MyTable where FieldX='aaa'An exception happens. Now I need to attempt to determine what went wrong:1. Cable was cut2. Syntax error in SQL3. PC where SQL Server is running crashed4. Timed outI need to attempt to recover from this issue. I have basically 2 options: It is a glitch that self corrects after a period of time, so I can just go ahead and retry the operation a few times. Option 2: It is something permanent, so no matter how many times I retry, the error will persist.
View 3 RepliesDevexpress - Making A Call From One Usercontrol To Another Form
Aug 28, 2010I have a tabcontrol that creates tab pages from a "User Control" I created (a separate form in vb.net) using this code: (MainTab is the separate user control I created which has text boxes etc in it)
Dim tmpTab As New MainTab
myTabControl.TabPages.Add()
Dim tmpTabCount As Integer = myTabControl.TabPages.Count
myTabControl.TabPages.Item(tmpTabCount - 1).Controls.Add(tmpTab)
myTabControl.TabPages.Item(tmpTabCount - 1).Text = "Untitled"
I'm using the devexpress xtratab control so the code might look a bit different than the default vb.net tab control.
Now in my MainTab user control file file, I can't for the life of me figure out how to call a control in the form1 where the xtra tab control is placed on. "Me.Parent.Dispose" works for closing the tab when executed via the MainTab control, but that's as far as I can get for communicating with the parent from.
I'm not sure if I have to reference something in the MainTab user control or what in order to communicate with any objects on the default form1.
DevExpress Accelerator Keys Not Showing In XtraBars
Dec 3, 2010I'm using DevExpress 2010 vol 1, VS2010 and VB.NET. In my form I have a xtraBar which is used to create the application main menu. Each of the menu items were carefully captioned using the ampersand char (&) to create the keyboard accelerator key, so when user press ALT key and hit the accelerator key the menu is shown. The problem is I can't make the underscore show in any caption. For instance, my first menu "File" has caption "&File", but the "F" is never underscore, and pressing ALT + F doesn't work either.
